ROTARY ENGINE.

Specification of Letters Patent. Patented Sept. 23, 1919,

Application led April 21. 1919. Serial No. 291.441.

.provision of an organized lmechanism adapted to be usedto advantage not only in a rotary steam engine but also ina water force pump, an air pump and an internal combustion engine of the rotary type.

Other objects and practical advantages peculiar to my invention will be fully understood from the follow-ing description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which: v 4

Figure 1 is a side elevation of the rotary engine constituting `the best practical embodiment of my invention that I have as yet devised.

Fig. 2 is a longitudinal vertical section illustrative of the interior construction of the engine.

Fig. -3 isa vertical central section taken ,at right angles to Figs. 1 and 2.

Figs. 4 and `5 are enlarged detail sections illustrative of the blade mounting.

Fig. 6 is an enlarged perspective `of the double ported valve `of the engine.

Similar numerals of reference designate lcorrespondiiilg parts in all the views of the drawings.

In `the present and preferred embodiment of my invention, I employ a support 1 for the exterior casing ofthe engine, and standards 2 or'maintaining in proper position the rotary member of the engine. I also prefer to have the exterior casing of the ening the invention. Located as best shown in Fig. 2 are groups of cylinders :6. y At 7 are conduits connected with the cylinders 6. The ends or heads of the inner cylinder are designated `by 8, Fig. 8, and at 9 are rings secured to the inner cylinder and forming walls against which annular metal packing members 10 bear as illustrated. At 11, Fig. 3, is a tubular journal for one side oi the inner cylinder, and at 12 is the nonrotating shaft complementary Ito the stal.tionary arms 13 disposed inside of the inner cylinder.

In each of the cylinders 6 is disposed the piston 18 of an exhaust valve 14. It is essential that these valves 14 bear Hush in apertures 14 in the wall 3. Each valve 14 is 4provided with a stem 15, of angular form yin cross-section, disposed in an angular conduits which are provided for the supply of steam. An exhaust pipe or :drain 23 is provided as an adjunct to the said conduits 22.

When steam is let into one of the` conduits duit 7 and entering the cylinders .6 at one side of the engine, closes and retains in closed position the valves 14 of the pistons 16 in said cylinder. At the same time the steam exhausting through the other conduit 22 will create a suction in `the other yconduit and therebycontribute to the opening of the valves 14 at the other side of the engine, so as to permit the exhaust ,steam `to enter the adjacent exhaust chamber 5.

The ports of lthe valve20 are numbered G0, 61, 62 and 63, Figs. 2 and 6. When said valve is in the position shown in Fig. 2, steam entering the port 64 from the supply ,conduit passes through port 61 to `the righthand conduit 22, Fig. 2, and at `the same time lexhaust steam from` the left-hand con- ,duit 22 passes through the port 62, which ,extends partly around the valve to the pipe 23. When the valve 20 is turned through half of a revolution to reverse the en ine, live steam from conduit 19 will pass rom the longitudinal bore 64 in valve 20 through the port 60 to the left-hand conduit 22, and at the same time exhaust steam from the right-hand conduit 22 will pass through the port 63 to the pipe 23. Y Y

By reference to Fig. i3 it will be noted `that 24 is a shaft fixed to one of the heads 8 of the inner cylinder. Also that 26 are stationary shaft portions, and 27 are the inwardly-reachingarms on the blades 28.- The Vblades 2 8 form walls of the steam chambers in conjunction with the circular wall 8a of the inner'cylinder.

The inner and rotary cylinder-comprises spokes 30 liXed to the circular wall 8a.

f There are preferably six of the stationary arms 13, and the spokes 30 are adapted to swing about pins V30a carried between the Y arms 13 of lthe two pairs,- Fig.'3.

On their outer and side'edges theblades 28-are provided with suitable packing, as in-V dicated by the dottedlines in Fig. 3.l

Y In conjunction with the blades 28 I provide metallic packing glands 31, of rocking type, best shown in Figs. t and 5,'which rocking glands are adapted to slide upon the "blades 28l in the direction ofthe length of tenanc'es' the' piston may be rotated, in eitherV direction and'may be 'quickly and'easily reversed when necessityfdemandsl The operation'oftheY engine will be attended the rotation of the inner'` cylinder including the `VVwall' 8a aboutthe stationary-shaft' portions 12, and incidental to :such rotation of the. cylinder, the blades 28` will be yrotated or moved about the center allorded by lthe shaft y portions 26. Y Y .y Y It will be readilyinotedthat the inner cylinder, the blades, andthe parts complementary thereto may-'be employed in combination and to:adi'fa'ntage1in` a force pump v for water or otherliquid, 'an*air'p'ump, an internal VVcombustion* engine, and analogous apparatus.

I-have enteredinto detailed: description of the construction andrelative arrangement ofthe elements embracedA in the present em-` j bodiment of my invention,` injorder to`im-l V parta` full, clear and exact understanding .fofthe said specific embodiment. Ido `not Gopies or this patent may be rottaiinedror desire,f however',},to be V'understood as con-y fining myselftothe said specific construction u v and relative 'arrangement'of parts, since `in the future practice of the invention various changes in the form; and arrangement may be made as clearly fall within ythe scope of `my appended claims.

Having described my invention, what I claimrand desire to secure byLetters-Patent, is: v Y
